Some cookies won't delete. one is sweetim.com which is malware, and seems to import or prevent the deletion of other malware cookies.

Sweetim.com and ones from mozilla and yahoo won't delete even when I try to delete "all" cookies. When I use the delete cookies option all except sweetim.com seem to have been deleted, but they reappear after firefox restarts. How can I delete them, or at least the sweetim.com.? Sweet.im seems to have come in when I unknowingly downloaded sweetpacks hijacker. I looked in about:config and there is a lot of sweetim stuff, but no way to delete them. I have turned off allowing third party cookies, before I did that, a bunch of unwanted cookies reapeared when firefor restarted. This subject is on the internet, but the suppossed answer just directs to unhelpful websites..

Chosen solution

hello, go to the firefox options > privacy panel & choose "use custom settings for history" in order to control that...
